. EXTENsiIoN TABLE.

.Applicationl filed .T une .15,

Be it known that I, JOSEPH HLozEn, a citizen of the Republic ofCzechoslovakia, residing at Cleveland, in the county of Cuya` hoga andState of Ohio, have invented cera tain new yand usefuly ImprovementsinEXtension Tables, of which the following is a l specification,reference being had to the ac- 15, 'i extendedto its full length or-collapsed with companying drawings.

This invention relates to ticularly'to extension tables.

The general object of the invention is to tables, and par- *provide anextension table which is relatively simple in construction, which may becheaply made, and which may be relatively but a minimum of effort. l

A further object is to provide. a construction of this characterembodyingva main table top with a supporting frame and legs or othersupports,` and a plurality of sets of leaves, one for each side of thetable, `normally housedl beneath the main table top but adapted to beshifted outward to extend the table, said leaves when extended lying nflush with the main table top; and provide main table top may belraisedv in order to permit the superimposed leaves to be shiftu edbeneath the main table top.

Other objects have to do with the details of construction andarrangement of parts as will hereinafter more fully appear.

My invention `is illustrated in the accompanying drawings, whereinFigure 1 is a side elevation of the table folded; I

Figure2 is a fragmentary longitudinal sectional view of thel tableexpanded and showing in dotted lines the positionsv taken by lthe leaves15 and 22 whenvthe table is being expanded; l

and disposed at the middle thereof'is a trans# i verse supporting member13 which is pref.v erably madein. two sections and is of woody?, if fand which is formedwitli downwardly flaring sockets 141 in its uppersurface.. ``Rest-` ing upon this member 13 is theymaintable-,if` top 15which is provided atopposite l ends 5,

with downwardly projecting pins.1'`eXtendv ing intolthe sockets 1li.These pins are pre-k f erably ofy iron. This connection ofthe table y.top to the supporting member 1 3 permits 'the table top 15 to beraisedorfloweredtola certain extent vand to.l be rocked; upon av fulcrum2 aswill be later described.

Coacting withthe sections20- land havingsliding engagement therewith by lmeans oftongues andl grooves aref` the slide sections 21, and engaging withtheslide sections 20a are the slide sections 212%.` lt will beunderstood, of course, that the slide sections 2O and 2l arey extendedin one direction when the table is pulled out, while the slideAsections20L and 2la are'extended in the opposite direction. l

y v(lla-rried by the slide sections20 on one yside ot the tableis a leaf22, which leaf-has l attached to its under side at its butt end the`downwardly extending hinge member 23 .whichI is disposed between ears24- having horizontal upper edges, these ears 2d# being mounted upona'plate 25 which is attached to the-upper lace oit' the correspondingslide section soinewhat inward troni the extremity tions 20. i I

Y Y, the slide sections 20TL by a like hinge conneci slide sections'2'0are upwardly inclined to award the outer ends and that the grooves ofthis slide section 20V. lt will be seen that the leaf" isthus elevatedabove the slide secrl. y.like leal .22a is` mounted upon Frein Figure2it will he seen that the v 19` are downwardly inclined relative tohorizontal plane. fllhesaine is true, oi course, ol the slide` sections20a. The purpose of this will hereafter appear.

Attached tothe extremities ot the slide sections 2l is the leaf 26, andit will be noted from Figure 2l that the slidel section 2l has its upperledge inclined upward and forward from its butt end for a certaindistance, as lv`at 27, but that rtroin'the point 28 the upperv edge ofthe slide sectionv2lis`horizontal. The sections 2l are yalso `upwardly40.-

and outwardly inclined. What is true or the slide section `2l is equallytrue of the Vslide sections 2ln and of the leaf 26a.

1iittachedtto' each leaf ,26 and extending i downward therefrom adjacentthe outer in'ar-f inone direction the end of the arm 33 will inoveupward.

- gin of' thel leai'is a depending member 29 adaptedwhen the leal` 26 isclosed to close in the ends of the table beneath the tabletop Passingthrough this depending member 29is a shaft 30 which is supported inhearings 3l,` this shaft being provided at its outer end with a handle32 and at its inner end with a lcurved crank arin 33 ca rying at its endthe --ro'llergfA A spring` 35 is'connected to the crank shaftf30 so asto cause the crank arin l33to normally lie ina horizontal plane.

lwhen, however, the handle 32 is oscillated TWhen the leaves22 and 26and 22a and 26l are disposed beneath the table `top l5 in thepositionjshown in FigureB, these crank 33 lie immediately heneathfthe'cut-away por-l tionslfof the transverse supporting meinber 13, andjobviously any rotation of the crank shaftby Ineans ot the handle 32 willcause the upward movement oit' the leaves 22 and 26 or 22l and 26a.

ln the operation of this device, assuining l that the leaves aredisposed beneath the table top l5, theirtheparts have Athe positionshown in Figure 3 and both leaves 22 and 26 on one side and both leaves22'LL and 26 onrthe other side are disposed inthe space between theYtable top l5 and the upper edgev iiacesot the slides andlguides lf?, 2Oand 2l and 13, 2Oa and 2la,`the table top resting` upon and beingsupperted by the upper tacept the,

member 13 and upon the several leaves. Now

Thiscliiis up on'the leaf ,2f/dazedthe1leaf22and npwai l' on one margin 'ot the 'table top so thatthe tabletopA ifnlcruins on itsother margin. the time torce applied, as 'for in-Lstance to thev leaf `2Gor"to thedep-ending nieinber 29, 'to vdraw thisend ot the table outward. riphis extends the slides 20 and 2li.v lfVhenthe leal 22 has been drawn' suliiciently ward and beyond the leaf 22,theleaf 22 wi drp into positionbehind ltheigdge of tha'. v leaf 26'andthe parts will occupy-the posi;v

It equally possi-ble temere! lydraw the leaves 22 outward from beneath the table, top, leaving thevleafv 26 beneath 'he lealQ 22'. 1While, I haveillust atedaIife'xK-rvtention tablepwith tourleaves, will un# derstood that'a greatervnuinber, of, lea-,ves might be used it' desired, the saine principle ofoperation being preserved.. 'y l Thespring 35, Nas soon as'the' handle.32r isreleas'ed, acts to return the cranlrfghatfj to its initialposition withy the arniv in all tion is repeated for the other side of.the leaves have been iulf" these 'legs beingheld either in' a hori-v taroutward, the tablev top laA will* drop ontok the p'roiecting ears or"thehin e and whenl the leait 26 has been drawnsurv ciently :out-g may'bedrawn out so asr lto expose theI leaves. 2G and 26?, vet it is notneessary.to,do` thisl rextend the n. table to its;

approximately horizontal position. When it is desired to contract thetable, the handle 32 is operated to oscillate the shaft and raise thearm 33. This arm 33, when the talble is fully extended, bears againstthe under side of the leaf 22 adjacent its free edge, and when thisshaft 30 is lifted, the arm 33 will raise the free edge ofthe leaf 22 soas to permit the leaf 26 to slide in underneath the leaf 22. As itslides in beneath the leaf 22, it raises up on this leaf and on thetable top 15, the roller 34' rolling along the under face of the leaf22. If it then be desired to still further contract the table, theroller 34 is moved upward by rotating the shaft 30 until vthe tab-le top15 is lifted sufficiently to permit the butt end of the leaf 22 to beinserted beneath the table top. Then the slides and leaves are pushedhome beneath the table top and the legs 36 turned upward. Thus the partsare brought. back to a fully contracted position. Of course, what istrue with regard to the contraction of the leaves 26 and 22 appliesequally well to the leaves 26a and 22@l on the opposite side of thetable.

lVhile l have illustrated the supporting frame of the table as beingmounted on the legs l2, I do not Wish to be limited to this, as theframe might be mounted upon any supporting structure, as for instance a`pedestal or compartmented supports, as in a desk. Neither do I wish tobe limited to the details of construction and arrangement of parts asillustrated, as these might be varied in lmany ways without departingfrom the spirit of the invention.

I claim 1. An extension table comprising a supporting frame, a table topcarried thereby but having vertical and tilting movement, a transversemember mounted upon the supporting frame at the middle thereof and uponwhich the middle of the table top normally rests, fixed upwardlyinclined guides carried by the frame below said member, movable upwardlyinclined slides slidingly engaging said guides and movable outwardtherefrom, a leaf hinged at its inner edge to said slides and hingedlysupported with its inner edge in spaced relation to the upper edges ofthe slides, said leaf being normally disposed beneath the table top, asecond set of upwardly inclined slides connected to the first named setof slides and having sliding engagement therewith, the outer endportions of said second set of slides being horifirst named leaf, andmeans whereby the` table top may be raised to permit the superimposedleaves to be shifted beneath the table top.

2. An extension table comprising a supporting frame having a transversemember, a table top resting upon the supporting frame, the table tophaving downwardly extending dowels and the supporting member havingupwardly contracted sockets which said dowels rest whereby the table topmay be moved vertically or tilted with inv reference to the transversemember, xed

upwardly inclined guides carried by the frame below said member, movableupwardly inclined slides slidingl engaging the guides and movable outwartherefrom, a leaf hinged at its inner endto an intermediate portion ofsaid movable slides and hingedly supported-With its inner edge'in spacedrelation to the `upper edges of the slides, said leaf being normallydisposed be neath the table top, a second set of upwardly inclinedslides having sliding engagement with the first named set, a second leafcarried upon the outer end portions of said last named slides andmovable intoposition beyond the first named leaf, the table top and thefirst named leaf dropping down into position behind the second namedleaf and flush therewith when the leaves are pull-ed out, and meansoperatively carried by the second named leaf and projecting beyond theinner edge of the second named leaf whereby the first named leaf may beraised to permit the second named leaf to be slid beneath the firstnamed leaf and. whereby the table top may be tilted to permit thesuperimposed leaves tobe shifted beneath the table top, said transversemember having a thickness equalto the thicknessof the two leaves'.l j
